Improvement in drop-hammers



UNITED STATES JEFFERSON AUGHE, OF DAYTON, OHIO.

IMPROVEMENT IN DROP-HAMMERS.

Specieation forming part of Letters Patent No. 55,976, dated July 3, 1866.

To all whom 'it may concern.-

Be it known that I, JEFFERSON AUGHE, of Dayton, in the county of Montgomery, in the State of Ohio, have invented a new and Improved Mode of Manufacturing Shares and Mold-Boards for Plows; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in useing a swaging-machine, with suitable dies, to manufacture shares and mold-boards.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Figure l represents a back view of the swaging-machine, the body of the hammer and the dies being shown in section. Fig. 2 represents a face view ofthe under die for forming the share. Fig. 3 represents a View of the dies used in swagingthe shares.

A A A represent the frame of the machine, which is constructed in the usual manner; C

O, the guides, which are secured to the plates B and D, and these are attached to the crossbars of the frame.

The shaft on, has bearings at u n, and sup ports the pulley I, which pulley has a notch, by w hich the arm K, moved by the lever O, causes the pulley to be moved or not at the pleasure of the operator. To the shaft m is attached a ratchet-wheel, which is held by the catch S when it is desirable to hold the hammer up for any purpose. To the pulley I is fastened a rope, It. This rope passes over the pulley Q, and thence to the hammer E.

To the shaft of the cog-wheel M is attached a crank, N, and when otherwise used apulley is attached, whichl is driven by a belt. The wheel M gears into the wheel L, and thus the pulley I is moved.

E is a ponderous hammer, hollow through its center for the bolt G, by which the die is have a square orice for the reception of the lower end of the hammer, and when placed in position are firmly bolted. The concave dies F and afare firmly secured to a piece of timber in the earth in a practical machine.

Operation: The power is applied at N, the rope R winding on the pulley I, and thereby raising'the hammer to a proper height, Where it is held by the catch S. Then the steel plate, heated to a red heat, is placed on the under die, and by a movement of the lever O the hammer falls; and this operation, -two or three times repeated, gives form to the share or mold-board, as the case may be.

Any form of machine by which the hammer may be elevated, whether by an arrangement of pulleys operated by hand, water, or steam power, or the use of steam direct, may be used 'for the purpose, as I make no claim as to the manner of elevating the hammer.

In forming the share, a, Fig. 3, is attached in the manner of the die F, and ct is-putin the place of F. The mold-boards and shares thus formed are perfectly uniform, not liable to Warp from tempering, readily polished, be,- cause no hammering is done by which the surfaces become indented, and the operation is effected in much less time than by the usual processes.

Having thus fully described my invention, what I desire to secure by Letters Patent is- 1. The mode of connecting a die to the ponderous hammer E of a sWaging-machine, substantially as herein described and represented.

2. The arrangement of the dies F F', the hammer E, and bolt G, substantially as described, and for the purposes specified.
